New Rapid Compression Machine

Figure 1. Photograph of the new RCM facility showing the mixing chamber, manifolds and the RCM

The new RCM facility consists of a rapid compression machine, a flow control/supply system, and a mixing chamber. Both the RCM and the mixing chamber along with the manifolds have a provision for heating up to a maximum temperature of 420 K.

Figures below show the new RCM facility schematically.

The new RCM facility is capability enhanced to attain higher end of compression pressures and wider compression ratios. Several other improvements from operational point of view are also incorporated.
